Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to, for example, an office or the like, a plurality of desks arranged side by side between a plurality of desks arranged side by side. The present invention relates to a device for connecting adjacent panels either directly or via an intermediate column erected between the panels when a partition panel is provided.

[Conventional technology]

Conventionally, to connect panels arranged side by side, a strip-shaped connecting plate is hung over the upper end surfaces and the lower end surfaces of the panels whose side end surfaces are abutted with each other and screwed or two screws are used. Each panel is fixed by screws to columns provided between the panels (see, for example, Japanese Utility Model Publication No. 63-44562).

[Problems to be solved by the invention]

Since the conventional method is performed at a panel installation site, the connecting operation requires much labor and time.

[Means for solving the problem]

According to the present invention, the above object is attained by the following means.

Along with a concave groove in the longitudinal direction at least on the upper end surface of the panel, an engaging hole is cut out near both ends of the bottom surface, and the groove extends across the concave groove of the two panels whose side end surfaces abut each other. A first hook formed at one end of the tightening plate is engaged with the engaging hole of one of the panels, and connected to the other end of the tightening plate via a toggle link. A second hook formed opposite to the first hook at an end of the hook plate remote from the first hook is engaged with the engagement hole of the other panel, and the tightening plate is recessed. When the toggle link is fitted in the entry groove, the pivot point of the toggle link to the tightening plate is located outside the pivot point of the toggle link to the hook plate, and is located closer to the bottom surface of the concave groove. A panel connecting device characterized by the above-mentioned.

 Further, the above-mentioned problem is also solved by the following means.

A plurality of panels each having a longitudinal recessed groove formed at least at the upper end face and having engagement holes cut out near both ends of the bottom face are formed by directly abutting their side end faces, or an intermediate pillar material. When connecting via one of the panels or the intermediate pillars, the connecting metal fitting having an upwardly channel-shaped and engaging groove at the tip end is fitted into the concave groove of the other panel. In the recessed groove of the other panel, a hook that engages with the engagement hole at the outer end of the lower surface and a lever that is pivotally connected to the inner end of the upper surface so as to be rotatable upward are provided. A fastener having a base end of a toggle link pivotally mounted at an appropriate position of the lever, a tip end of the toggle link being pivotally removably pivoted to the engagement groove of the connection fitting, and When it is pushed down into the recessed groove, it goes to the lever of the toggle link. Pivot points, connecting device panel, characterized in that the person outside than pivot point to the lever of the fastener, and were to be located on the bottom side of the recessed groove.

In the latter panel connecting device, it is preferable that a linear connecting fitting is fitted over the recessed groove of the two panels whose side end surfaces are butted together.

In this case, a hook for engaging with the engagement hole of the panel is formed at one end of the connection fitting, and an engagement groove for pivotally supporting the tip of the toggle link is formed at the other end, and the hook is directly engaged with one of the panels. And the other panel may be fastened by a fastener.

Further, in the latter panel connecting device, a plurality of connecting metal fittings each having an engaging groove formed at the front end thereof are protruded in different directions from the intermediate pillar material, and the corresponding number of panels are connected by fasteners. It is better to wear it.

Further, when the side end surfaces of two panels having different heights are abutted and connected to each other, an engagement groove is formed at a front end portion from the side end surface of the high side panel which matches the height of the upper end surface of the low side panel. A connecting fitting may be protruded, and the lower panel may be attached to the connecting fitting with a fastener.

(Operation)

According to the device of the present invention, since the connecting device is configured with the toggle joint, the hooks of the connecting device are directly engaged with the side end surfaces or in the engaging holes of the respective panels arranged and connected via the intermediate pillars. Engage and forcibly push the lever of the fastening plate or fastener to the bottom side of the recessed groove, if the side end surfaces of both panels or the side end surface of the panel and the intermediate column material are strongly pressed against each other, the panel It is possible to firmly connect each other or the panel and the intermediate column material.

Once the tightening plate or lever is pushed down to the bottom side of the recessed groove, the toggle link is located at the bottom side of the recessed groove beyond the dead center of the pivot mechanism when pushed down, so some force is applied. Unless the panel is lifted, it will not separate during use of the panel.

A connection device, a connection fitting having an engagement groove formed at a distal end thereof,
The panel can be connected to each other directly or via an intermediate column member by constituting the panel with a fastener which is detachably connected to the panel.

A plurality of connecting fittings are protruded from the intermediate pillar in different directions, and the panels are connected to each other by fasteners, so that the arrangement of the panels is connected in an arbitrary shape such as an L shape, a T shape, or an X shape. be able to.

Further, panels having different heights can be directly connected to each other by the connection fitting and the fastener.

First Embodiment FIGS. 1 to 3 show a state in which the upper ends of adjacent panels (1) and (1) are connected to each other according to a first embodiment of the device of the present invention. Is a frame in the panel (1), (3) is a decorative plate in the panel (1), (A)
Is a connecting device.

U-shaped recessed grooves (4) are formed in the upper end surface and the lower end surface (not shown) of the frame (1), and rectangular engagement holes (5) are formed near both ends of the bottom surface (4a). (5) is perforated.

(6) is a tightening plate in the connection fitting (A), which has a channel shape having a width capable of being fitted into the recessed groove (4) of the panel (1) without slack, and has a left end (hereinafter, the direction refers to the drawing). ), A first hook (7) which is bent downward to the right after being directed downward is formed.

Near the right end of the upper surface of the center piece (6a) of the tightening plate (6), and when the side edges of both panels (1) and (1) abut each other,
At a place separated by more than the distance between the two engagement holes (5), (5), one parallel rod (8a) of the I-shaped toggle link (8) (upper in FIG. 1) is provided with the width of the tightening plate (6). Bearings aligned in the direction (9)
With (9), it is pivoted directly on the central piece (6a).

A hook plate (10) narrower than the tightening plate (6) is attached to the other parallel rod (8b) via a spacer (11) through a bearing (12).
The first hook (7) is attached to the right end of the hook plate (10) below the hook plate (10) when the hook plate (10) is parallel to the tightening plate (6). A second hook (13) is formed opposite to the second hook (13).

To the left of one parallel rod (8a) of the toggle link (8) at the center piece (6a) of the tightening plate (6),
A hook plate (10) when parallel to a) and a window hole (14) through which a center rod (8c) of the toggle link (8) can pass through are cut out.

The length of the center rod (8c) is such that the distance between the first hook (7) and the second hook (13) in the mounted state shown in FIG. 2 is from the adjacent end of each panel (1). Each engagement hole (5)
The distance to (5) is preferably set to be substantially the same as or slightly smaller, and the difference between the two panels (1) and (1) is preferably tightened together.

In the first embodiment described above, the connecting device (A) is inserted into the recessed grooves (4) and (4) of the panels (1) and (1) whose side ends are in close contact with each other.
